Data Physics designs electrodynamic shaker systems that allow testing of a complete range of batteries for electric vehicle development programs.

The Data Physics SignalForce™ ED shaker featured here is capable of testing payloads of over 750 kg on the purpose-built head expander and slip table assemblies.

This dedicated vertical system is one of two matching test systems to feature a Data Physics’ LE-1316-3 shaker, which generates up to 60 kN force (Sine and Random) and was built with several modifications to accommodate the battery test environment.
After completing quality assurance and final customer acceptance testing in our Corona, California factory, this system was delivered to Europe for integration at the customer site.

The guided vertical head expander has a mounting area of 2.5 m x 1.5 m and was FEA modeled to accommodate testing to 2 kHz, when necessary. The specific size and shape allow for testing the latest EV batteries which typically reside in the floor of the electric vehicle. The head expander design features special external guidance and load support for the head expander, protecting the shaker armature and test article in case the battery under test creates offset loads.

In the event a thermal runaway condition is sensed during testing, the system’s unique side panels and diaphragm act to protect the shaker from fire extinguishing agents, which are deployed to prevent a catastrophic fire.

Each battery testing system will be controlled by Data Physics’ latest-generation 900 Series vibration controller, incorporating distributed real-time digital signal processing and advanced control algorithms for accuracy and safety. The 900 Series controllers include software for random, sine, shock, and resonance dwell control.
